@joyofliving5352 3 месяца назад

Hi teacher, could you do a tutorial for relationship between ionic strength and pka for weak electrolytes (including biological environments)? There's this consensus that an activity coefficient is required in practical terms to be able to calculate dissociation equilibrium constant - as solution departs from ideal behaviour. If you can derive the equations and do few examples, and indicate when low or high ionic strength may or may not affect pKa or pH, that's helpful.

can someone pls answer my question ? which has lower ph nh4cl or h2s03 ? i googled it and nh4cl is 4.6-6.0 and h2so3 is 5.1 . this question came up on the exam that the whole country took . we never studied if the acidic salt had a lower ph than a week acid or the other way around. most teachers said the two answers should be correct but the ministry of education (who wrote the exam) said no theres only one correct answer and im dying to know which one it is.

@stephenfajen5837 2 года назад

Can someone explain why at 9:08 we can just cancel the x value. I get that he said that 10^-5 is small, but what does small mean? Is there a certain value where its considered too small to really be relevant? Can that x value just always be disregarded no matter the number?

@sewermonster6162 2 года назад

Basically, what happens is that if the x-value is found to be extremely small, then you can make an assumption that x won't throw your answer off by much and just disclude it from the equation.

@god2958 Год назад

can someone help me? A saturated aqueous solution of salicylic acid has a concentration of 0.018 m at 25 °C. Calculate the pH of the saturated salicylic acid solution. how do i calculate this and how do i find the ka if its not included.

@makemoneyonline_888 Год назад

Hey, I’d like to ask about Cl. Why didn’t we include it in the reaction ?

@kosarhashemi8645 Год назад

yeah i got lost there and on 4

@maxymtaras2464 Год назад

I guess the general gist of it is that Cl is a spectator ion because the compound is a salt, so its kinda like the water where you can ignore it because it would be important. However yeah still a bit confusing on when or when not does this happen.

@benjaminadams3813 3 месяца назад

At 9:08 you say "that because 10^-5 is pretty small, so we can ignore that x", why can we ignore that x? Also, how do you know when to use the positive or negative value to the +/- of the square root? Thank you in advance, sorry for the questions!
